Application of Accuracy Engraving Technique in the Complex Curved Surface Mould Processing

The advantages of the precise carving techniques in complex curved surface mould processing are studied. The small tools of carved machine can realize the small size processing which is unachievable for CNC and NC milling machine. The method using accuracy engraving machine to manufacture complex curved surface mould with small features is proposed, so the speed of mould processing is accelerated, the cost of new product development is decreased, the rapid manufacturing is realized and the traditional design method using only CNC and milling machine is improved. Finally, this method has been applied to the processing of a plastic mould and the application method is expounded.
